MANUFACTURE OF CASES FOR .EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 363,267, dated May 17, 1887.

Application filed May 10, 1886. Serial No. 901,760. (No model.)

To all whom it may concern: f

Be it known that I, WILLIAM B. WHITE, of Quincy, in the county of Norfolk and State of Massachusetts, a citizen of the United States of America, have invented a new and useful Improvement in the Manufacture of Cases for Eyeglasses, of which the following is a speciiication.

This invention relates to the manufacture of cases for eyeglasses, Ste., such as are described and shown in Letters Patent of the United States dated March 21, 1876, N o. 175,171; and the invention consists, in substance, rst in placing two pieces of suitable material-such as leather, Src., previously cut to the desired size and shape for the sides of the case-evenly together and between suitable clamps, then placing a metallic frame, which has previously been folded longitudinally and bent substantially into the proper shape, over the edges of the said sides, and then in a suitable press pressing and rmly binding the metallic frame closely down upon the edges of the sides, completing the case, which, removed from thepress,

is ready for use, all substantially as hereinafter fully described, reference being had to the accompanying plate of drawings, in which is shown apparatus for carrying out this invention.

Figure 1 is a perspective view of a press substantially constructed and arranged for binding the metallic frame upon the sides of the case. Fig. 2 is a perspective view of a receptacle in which the sides are placed preparatory to clamping them together; Fig. 3, a partial side and partial longitudinal sectional view of the clamp and the receptacle in longitudinal section, with the two sides of a case therein in 1ongitudinal section and clamped together. Figs. 4 and 5 are vertical cross and longitudinal sections, respectively, on lines 4. 4 5 5, Fig. l, with a case placed therein ready for operation thereon, and also in section. Fig. 6 is a plan view of Fig. 3. Fig. 7 is a detail plan view, to be hereinafter referred to 5 Fig. 8, a perspective view of a case all complete.

In the drawings, A represents a block or plate having a rib or raised portion, B, extending along three sides in the outline shown in Figs. 2 and 6, the inner walls, C, of the portion B corresponding in shape and size to the shape of the spectacle-case desired, and for the edges fof the sides of the case, before the metallic frame is secured thereto, to just iit in the space between the walls C.

E is the clamp, whichis formed of two parts or arms, a b, hinged together at d, having handles F; and secured to the end of each arm a b, respectively, is a thin plate, G I-I, of metal, each of which plates corresponds to the shape and outline of the sides for the case, but is a little smaller all round, as shown in Fig. 6 more particularly, in order to leave the edges f of the sides free for the securing of the metal frame thereon. The plate G is rigidly secured to its arm b and the plate H to its arm c by a pivot, y, on an offset, h, at its central portion, so that when the sides are placed between the two plates and the plates closed upon them they will be held firmly and closely together at all points except at their edges, as before described. The two plates G H are of equal size and attached to their respective arms so as to be exactly opposite each other.

.l is a press for pressing the metallic frame to and upon the edges of the side pieces, and is formed of two parts, K L, one of which, K, rests upon springs Z, which rest upon the flanges m of thelower portion, L, each of which springs encircles a bolt, M, screwinginto the iiangesm and passing freely through openings a in the part K,whereby thepartK can be freely moved up and down and be guided in s uch movements by the bolts M, the heads'p of the bolts limiting its upward movement.

The upper part, K, overlaps aportion, N, of the lower part, by which it is also guided, and each has a narrow shoulder, r s, which shoulders conform to the shape and size of the case when finished. The two pieces tu, forming the sides of the case, having first been cut to the required' shape and size and placed together, their face sides outward, are placed in the receptacle A, close against the end portion, o, of the rib B, which brings the two pieces evenly together. The two plates G H of the clamp E are then opened from each other by operating their handles, and preferably the one, G, placed under the side pieces, tu, and between them and the bottom w of the receptacle IOO A, and pushed up as far as it will go, its movements being limited and regulated by the crossprojecting pin mon the armb abutting against the end of the receptacle.

P is a central longitudinal opening or recess in the bottom of the receptacle, to allow for the insertion of the arm I) of the clamp. The clamping-plates are then closed upon the side pieces by operating the handles, and then the metallic frame or strip Q, which is rst folded longitudinally 'and bent substantially into the form desired for the case R, is then placed over the edges f of the two 'side pieces, as shown in Fig. 7, and the'ends b'. then brought toward each other and onto the edge pieces of the sides and there held. The whole is then slid endwise into the press J, between the shoulders r s and the walls d', as far as it will go, and thenv the upper part, Ky, of the press is moved down upon the lower "part in any suitable manner, which presses the metallic strip cr frame between the two shoulders r s and causes it to be rmly bound and pressed upon the edges of the case. When raising the part K, the case can be removed from thepress and used as desired.

It is preferable -to have the shoulders r s at their outer edges, f, approach each other a little to more firmly press or nip the edges g of the metallic strip Q onto the material of which the side pieces are made. ,v

By this process the sides of the case are evenly placed together and thererhe'ld, and the metallic frame placed around their edges and irmly secured thereto, all in a simple, quick, convenient, practical, and quite inexpensive manner.

c This invention is applicable to other forms of cases for eyeglasses, &c., than the one herein shown, as is obvious. l

Having thus described my invention, what'I claim is- That improvement in the manufacture of 4o cases for eyeglasses, spectacles, 85e., composed of two sides of a suitable material anda metallic edge frame, consisting of rst placing the two sides of the case evenly together at their edges, then clamping them together at their central portions, and when so clamped placing the me- WM.
